The answer is no. Because solution (a,b) means x=a, y=b.and we have a-b=5. And (b,a) would mean x=b and y=a but then x-y=b-a=-(a-b)=-5≠5. So the pair (b,a) is not a solution.
−2(13x−15)
distribute by multiplication -2 to 13x and -15
-26x+30
Answer:
No she is wrong
Step-by-step explanation:
The correct answer is 320
The height of the building is 3 feet
<h3>How to determine the value</h3>
From the information given, we have that;
- Angle of elevation = 4. 72 degrees
- hypotenuse side = 36 feet tall
- Building height is the opposite side
Using the sine identity:
sin θ = opposite/hypotenuse
Substitute the values
sin 4. 72 = x/ 36
cross multiply
x = sin 4. 72 × 36
x = 0. 0822 × 36
x = 3 feet
Thus, the height of the building is 3 feet

Answer:$99.25
Step-by-step explanation:
Each by a sweatshirt including Amanda 3x25.50=$76.50 ,2 of them by popcorn so 2x4.75=$9.50, Amanda buys a hotdog 1x3.50=3.50, One friend bought nachos so 1x3.00=$3.00 and then Each girl bought a drink so 3x2.25=$6.75.
You have to add up all the totals which is 76.50+9.50+3.50+3.00+6.75 once you add those you get $99.25 that’s the total amount spent at the game.
